Hello, I'm trying to solve an periodic ecuation involving several harmonics
(Style ACos(x)+BCos(2x)+...==K). Mathematica can't let me us 'Solve'
function, so it gives me the error:
Solve::tdep: The equations appear to involve the variables to be solved for
\
in an essentially non-algebraic way.
To arrange this, i'm making a little program involving FindRoot function to
find at least two roots from the ecuation in the first period. But I would
like to know if there are some other method to do this more easily.
Thanks a lot
